一、原子核外电子运动状态1.电子云:用小黑点的疏密来描述电子在原子核外空间出现的机会大小所得的图形叫电子云图。离核越近,电子出现的机会大,电子云密度越大;离核越远,电子出现的机会小,电子云密度越小。电子层(能层):根据电子的能量差异和主要运 First, the movement of the nucleus outside the electronic state 1. Electronic cloud: the density of small black spots to describe the electronic space outside the nucleus in the size of the opportunity to get the resulting graphics called electronic cloud. The closer the nucleus, the greater the chance of electrons appears, the greater the density of electron clouds; the farther away from the nucleus, the less chance of electrons appears and the smaller the density of electron clouds. Electron layer (energy layer): According to the energy difference of electrons and the main transport
